NI-MH&NI-CD Battery charger
 
General Introduction
These Smart Chargers are specially designed to safely and quickly recharge the NiMH/NiCD battery packs. Automatically sensing the packs' voltage, it adjusts its current (AMP) output accordingly and later automatically shuts itself off when the pack is fully recharged. Be equipped with a smart LED that indicates charging condition; Be with Short circuit protection, Battery reverse connection protection and over voltage protection/Temp Protections.

Charging process description(Single cell for example)
 
0-T1:
Wake up stage. When the voltage of the cell is lower than 1.0V±0.1V, the charger will use pre-charge current to charge the battery.
T1-T2:
Current ramp up stage. When the voltage reach to 1.0V±0.1V, charge current will ramp up from wake up current, and at the end of this stage, the current will be set to fast charge value by the MCU.
T2-T3:
Constant current stage. Charge battery with fast charge current, until the condition of -△V（3~5mV）voltage, △T（18℃）or Tmax（60℃）occured, Constant current stage ends.
T3-T4:
Trickle charging stage. The charger will use supplementary current to charge the battery.
T4-:
After the trickle charging stage, the red charging light goes out and the green-light turns on. If the battery has been detected is full-charged, the charger will use pulsed current to charge the battery to balance the loss of battery self-discharge.
